application filed July 19,

1917. Serial No. 181,565.

To all whom it may concern:

Be it known that we, HARRY D. LATHROP and WALTER H. PAULSON, citizens ofthe United States, and residents of the city of Chicago, county of Cook,and State of Illinois, have invented certain new and useful Improvementsin Can-Reversing Mechanism for Can-Washing Machines, of which thefollowing is a specification.

Our invention relates to improvements in can reversing mechanism for canwashing machines, the present application being a division of ourpending application, Serial No. 149,102, filed February 16, 1917, forimprovements in can washing machines.

The object of this invention is the production of reversing mechanismdesigned for use in connection with milk can washing machines, whichwill be rapid and positive 1n operation, one which will permit of manualoperation at a minimum exertion on the part of the operator, and onewhich will be of durable and economical construction.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings, forming a part of this specification, and in which,

Figure 1 is a side elevation of a milk can washing machine equipped withcan reversing mechanism embodying the invention,

ig. 2, a slightly enlarged vertical long:- tudinal section of thedischarge end of t e machine, and

Fig. 3, a detail section taken on line 3-3 of F1 2.

The preferred form of construction as illustrated in the drawings,comprises a suitable framework 10 in which are provided superposedhorizontally extendin guides 11 and 12 for the cans and covers toliecleaned. Suitable mechanism is provided, operable by an oscillatorymanually operable lever 13, fulcrumed at 14, for efliecting intermittentfeedin or advancing of the cans and covers throng the machine, on theguides 11 and 12. In this intermittent feeding or advancing of the cansand covers through the mach ne, the same are subjected to a cleansing,steril zing and drying process, the mechanism for effecting suchtreatment of the cans same throu tion of the can reversing and coversand for advancing or feeding the h the machine, not bein claimed in thisapp ication, and hence detaildescription thereof is omitted.

, After the cans and covers have passed through the cleansing the sameare ready for discharge from the machine and to this end are passed fromthe guides 11 and 12 on to inclined guides 15 and 16, respectively, downwhich said cans and covers are adapted to slide by gravity. The canswhich are designated by the letter A, in the passage of the same alongthe guide 11, are in an inverted position, and as each can is dischargedor pushed from the guide 11, the same drops to osition in asubstantially semi-cylindrical formed can reversprocess, as mentioned,

mg member 17 which is arranged at the dishe member 17 is of a size tosnugly receive the can, end pieces 19 and- 20 being adapted to engagewith the opposite ends of the can to hold the same against relativelongitudinal movement. The normal posimember 17, as seen in Fig. 1, isone in which the same is adapted to receive a can discharged from theguide 11. Actuation of said member 17 to effect reversal of the can iseffected by means of a toggle,21 fulcrumed at 22, the opposite end ofsaid to gle' being connected at 23 with one end oi said member 17.Actuation of said toggle is efiected by means of a link 24 which ispivotally connected at one end with the lower end of an oscillatory arm25 fulcrumed intermediate its ends as at 26. The upper end of arm 25 isarranged in the path of a roller 27 carried by a reciprocatory rod 28having operative connection with the actuating lever 13, the arrangementbeing.

such that. upon oscillation of said lever 13, rod 28 will bereciprocated to carry the roller 27 into engagement with the upper endof arm 25, causing oscillation of the same to 'shown in Fig. 2.

by gravity.

the can reversing reaches this position, ity therefrom on to down whichthe same moves The up er end of the arm 25 is offset as at 25' in or orto form a shoulder which will assume horizontal position when the canreversing member 17 is in reversing position as seen in Fig. 2. Themovement of the roller 27 is such that, as the can reversin memberreaches reversing1 position, sai roller will travel on to the o 25 ofthe arm 25, as clearly der or portion and thus serve to posiseen in Fig.2, tively lock said versing member in can reversing position. Said canreversing member will not be permitted to return to initial or canreceiving position until the bar 28 carrying the roller 27 is movedrearwardlyzthrough manual tilting of the lever 13. hen this is done thereversing member will rock by gravity back to its initial position toreceive another can. Each subsequent can is similarly handled.

In order to lock the reversing member 17 in can receiving osition so asto adapt the same to withstan the rough usage to which the same issubjected by reason of the dropping of a can to position thereon thearran ement and operation of the to gie 21 is suc that the same passesbe on deadcenter position in the return roc ing of the reversing member17. This movement of the toggle to a-position be end the deadcenter isinsured by a wei t 24 rovided \li pon one end of the link 24, as clear yseen in 1g. 2. With this arrangement it will be seen that the pressureor weight of the can upon t e reversing member, cannot possibly effectswinging of the reversing member to can reversing position, suchswinging of said reversing member being effected only u on breaking ofthe knee joint of-the to g e which is effected through manual ti twigtof the lever 13 as before described. A er breaking of the knee joint,continued oscillation of the lever 13 causes the oscillatory movement ofthe reversing memberto efi'ect reversal of the' can. It will thus beseen that the can reversin member is at all times under the control 0the manually operable lever 13, actuation thereof to or from reversingposition being eflected only throu h manual actuation of said lever.

By ocating the axis of the reversing member intermediate the endsthereof, the space rizontal shoularm and hence the can relocked pastnecessary for the operation of the same, is reduced to a minimum, itbeing clear that with the axis located at either end of the reversingmember, a considerably greater space would be required to allow for theswinging of the member. Also with this arrangement, the parts are sobalanced that actuation of the can reversing member may be effectedthrough minimum exertion on the part of the operator, on the controllever 13.

While we have illustrated and described the preferred form ofconstruction for caring ourinvention into effect, this is capab e ofvariation and modification without ciRe parting from the spirit oi theinvention.

e, therefore, the precise details of construction set forth, but desireto avail ourselves of such variations and modifications as come withinthe scope of the appended claims.

Having described our invention what we claim as new and desire to secureby Letters Patent is:

1. In a can washing machine, can reversing mechanism comprising anoscillatory elementadapted to receive and reverse a can depositedthereon; means for effecting actuation of said reversing element, saidmeans comprising an oscillatory arm; a reciprocatory member adapted toengage with and rock said arm in actuating said reversing element; and ashoulderon said arm adapted for engagement by said reciprocatory member,when said element is in can reversing position, to lock the same in thisposition, substantially as described.

2. In a can washin machine, can reversing mechanism comprising anoscillatory element adapted, in the receiving position thereof. toreceive a can deposited thereon; means for oscillating said element toreverse the'can, said last mentioned means comprising a toggle; a stopwhereby said toggle is dead-centerwhen said reversing member is inreceiving position; and means for actuating said toggle, substantiallyas described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
